' STEIN, a citizen of the United States, residing at Lyndhnrst, in the county of Bergen and State of New Jersey, have invented certainv new and useful 1m 'rovements in Calculating-Machines, of w ich the following is a specification. This invention relates to calculating machines, such as that which forms the subject matter of S. patent to Alexander-Rechnitzer, Number 809,075, granted Jan. 2, 1906. In that machine, .as is usual in many other calculating machines, there is provided a series of indicating numeral wheels on a common shaft and means for returning all of these numeral wheels to their initial or zero positions. In this particular machine, the mechanism for this purpose is manually operated in both directions, and there are ,no means provided to prevent the continuation of the movement-beyond the position neces-' sary to be attained to bring the numeral wheels to-the zero position which osition is also the proper one from which to begin any calculating operation. 1

. .Itis the object of the present invention to provide such and similar zero-resetting mechanism" with improved meansfor limiting the movement in the direction for resetting the numeralwheels to the position which brings the wheels to zero, and for'automatically ref as turning the manual 0 crating devices to their initial positionsrea y for another resetting operation f 1 In the accompanying drawing in which is illustrated the present invention, together with so much 0 the plane of thebroken' line 22 of Fig. 1,

' looking to the left as indicated by the arrow.

Fig. 31s a vertical sectional view on a plane at right angles tothat of Fig.2.

through the verticalior barrel shaft above the pawl-yoke or wish-bone pawl, the barrel bemg sectioned on another plane, from the cam,

F. HAUsthe original machine as is Fig. 4 is a 1 horizontal sectional view on a plane cutting.

being .in the positions assumed at the end of the manual, zero-setting stroke or movement.

In the original machine there is a series ofnumeral. wheels .or disks of any desired numher to suit the capacity of the machines, of which only two are shown here, 'marked 6 and 7, such series being loosely mounted on a shaft 8, and each nuineral=whee1 having,

secured thereto or formed integral therewith, a mutilated gear 9, part of its teeth being removed, or omitted, as at 10.

. Parallel with the shaft 8'is a shaft 11 upon able bevel-gear, as at 14, with a vertical shaft 15, reaching through the top plate 16 and provided with-a crank-handle 17 for manual operation. Below the plate 16 the shaft 15 is incased in a fixed barrel 18 and a coiled spring 19 is located in said barrel, around the shaft, its inner end at 20 being secured to the shaft and its outer end, at 21 being secured to the barrel, ,so that the ten sion of the spring will always tend to unwind itself from around the shaft and turn the shaft to the right, or clockwise. tion of the shaft under the action of the spring is limited, so that the shaft must alwaysstop 1n a position to brin the gears 12 into place with their mutilate parts 13 opposite the nume'ralwheels', as best shown in Figs. 2' and 4, in the former of which the gears are shown in this position while in the latter the spring, barrel and shaft are similarly shown ,such'position being the initial or zero position of these parts,

".Upon the sh ft 15 is secured a disk 22 provided with diametrically opposite stop teeth 23 and 24, the-former having a radial face 25 and beveled face 26 and the latter a radial face 27 and a beveled face 28, the radial face 25 facing to the right and the radial face 27 to the left.

Pivoted to the casing is a'double armed U- sha ed or wish-bone pawl 29 whose arms 30 an 31 embrace yoke fashion the toothed disk 22 and have theirextremities at a distance apart sl-i htl less than the combined diameter oft e disk and length of the teeth 23 and 24v so that when the extremity of one arm rests against the radial face of one tooth,

.13, such shaft 11 being connected, by sui't- This rotathe other arm will rest on the outside of the {apposite tooth, as shown in Figs. 4 and 5, one tooth always serving as a cam to press the arm of the yoke outward and cause theradial face of the other tooth to abut against the end of the opposite arm. The shaft be ing impelled toward the right by its spring, the tooth 23 is so positioned or timed that it will abut against the end of the arm 29 just i when the mutilated portions 13 of the gears 12 are opposite to the gears 9 of the numeral wheels, all of the mutilated portions 13 bein in line with each other. When the numera wheels are'at zero, the mutilated portions 10 of the gears 9 are opposite the mutilated portions of the gears 12, as shown in Fi 2, and the rotation of the gears 12 will ave no effect on the gears 9 or the numeral wheels and vice versa, the rotation of the numeral wheels and their gears 9 will haye no effect on the gears 12.

In the operation of the machine, however, the numeral wheels are turned out of their zero positions to indicate various numbers,

- and when the operation is finished some or all of the gears 9 are turned to various positions. It may be that each one willbe at a different distance from the zero position and no matter what these positions may be, a gear of each of the wheels 9 which has been turned from the zero position will be opposite the mutilated portion 13 of a gear 12. By now turning the handle 17 in the direction opposite to the stress of the spring, for instance -to the left from the position of Fig.

. 4, the teeth of the gears 12 are brought into mesh with those of the gears 9 and the latter' will be turned until their mutilated portions come opposite the ears 12 when the turning of the gears 9 wi l cease, and the rotation of the gears 12 one complete revolution will bring all of the gears 9 into this initial or zero position (Fig. 2).

During the revolution of the gears-12, the

toothed disk 22 is turned, during the first half revolution of which turning, the beveled face 26 of the tooth 23 willslide' inside of the arm 30 of the voke-pawl 29 pressing that arm 1 release of the manual stress upon the handle will permit. the spring 19 to come into play and return the gears 12 and disk 22 to the position of Fig. 4 without disturbing the gears 9 or their numeral wheels, the action of the teeth 23 and 24 on the yoke 29 being the reverse of that before described.
